摘要
A method for estimating a diameter of an object of interest, includes extracting a sub-volume of voxels around a marker identifying a location of the object of interest (101) , and determining a segmentation result identifying an edge of the object of interest by a reactive-diffusion method (109) . The method further includes performing a boundary check on the segmentation result to determine whether the object of interest is solitary (110) , estimating a diameter of the object of interest from the segmentation result upon determining the object of interest to be solitary (108) , and extracting the object of interest by performing ellipsoid fit on the sub-volume (111) and estimating a diameter of the object of interest upon determining the object of interest to be non-solitary (108) .
